LIQUID-DISCHABGING GUN.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed July 17, 1918. Serial no. 245,338.

To all whom it may concern:

Be it known that I, PANKRACY WAsYnowrorr, a subject of the Emperor of Austria, residing at Chelsea, int-he county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Liquid-Discharging Guns, of which the fol: lowing is a specification.

The primary object of the invention is the provision of liquid discharging means for rifles whereby a mistv or. spray of desirable fluid may .be readily projected toward the enemy substantially in the path of travel of the missile thrown by the rifle and whereby the rifle with the soldier operating the same will be partially obscured from view while firing upon the enemy.

A further object of the invention is the provision of a gun adapted for projectlng fluid provided with closing means adapted for automatic operation subsequent to each discharge of the device.

A still further object of the invention is the provision of a squirt-gun attachment for rifle barrels that is easy and inexpenswe to manufacture and readily attached in position for use by the person in charge of the rifle while a safety appliance is provided for preventing the escape of any fluid from the squirt-gun when not in use.

The complete device will be hereinafter fully described as to the elements and op eration thereof, such description being in connection with the accompanying drawings in which like reference characters designate corresponding parts throughout the several views,

In the drawings:

Figure 1 is a side elevation of a rifle with my device mounted upon the barrel thereof, illustrated in its closed position;

Fig. 2 is a plan view thereof taken from the top or upper side of the rifle;

Fig. 3 is a side elevation of the rifle and my device showing the opposite side thereof from that illustrated in Fig. 1;

Fig. 4. is an enlarged central longitudinal sectional view through the device with the portions thereof illustrated by dotted lines iln their open position ready for discharging uid;

Fig; 5 is a bottom plan view thereof;

Fig. 6 is a transverse sectional view taken on line VI-VI of Fig. 4:;

Fig. 7 is a bottom plan view of the forward end portion of the device closed and with the closing means removed; and

Fig. 8 is a perspective view of the automatic closing means employed with the device, with the operating rod broken away.

My device may be employed for projecting fluid for any desired purpose but is espeeially adapted for attachment to a rifle such as 10, and herein illustrated mounted upon the barrel 11 thereof. A cylinder 12 is secured to the barrel 11 by means of straps 13 which are carried by the cylinder and clamped around the barrel in any desired manner as by bolts 14.

A tapered nozzle 15 is threaded in the open forward end of the cylinder 12 extend- 111g slightly in advance of the muzzle 16 of the rifle barrel and having a discharge passage 17 through which fluid within the chamber 18 of said cylinder is adapted to be projected by a tightly fitting piston or plunger 19. A head 20 is screw threaded upon the opposite rear end of the cylinder 12 through which the rod 21 of the piston 19 freely moves, the said rod being positioned axially of said cylinder. A suitable handle 22 upon the outer free end of the rod 21 is provided for convenience in reciprocating the rod 21 and its piston 19 for alternately drawing fluid intothe chamber 18 through the passage 17 and thereafter projecting the fluid outwardly through said passage after the usual manner of a squirtgun. I y

A cup-shaped cap 23 is hinged as at 24: to the forward end of the cylinder 12 adapted for closing over the nozzle 15 against said end of the cylinder. A block 25, adapted for closing the cap 23, is slidably mounted upon the bottom of the cylinder 12 by means of outwardly projecting tapered flanges 26 of the block positioned within parallel guides or strips 27 upon the bottom of the cy1inder. An operating rod 28 is attached at one end to the block 26 with its opposite end secured to the handle'22 whereby the block 25 is reciprocated simultaneously with the piston 19 at each movement of the handle 22.

The rod 28 freely slides through a laterally projecting lug 29 upon the bottom of the cylinder 12 while a groove 30 in the bottom of the block 25 accommodates the hinge 24: when the block passes thereover. When the handle 22 is drawn rearwardly, retracting the rods 21 and 28, the cap 23 falls open by reason of its own weight when the block 25 is released from the cap, it being noted that the hinge 2/11: is at the lower side of the members are positioned as indicated by dotted lines in Fig. 4 of the drawings with the cylinder 18 partially filled with fluid,- the forward movement of the handle 22 forces the fluid outwardly through the nozzle passage 17 and the forward curved end 31 of the block 25, which end is slightly arcuate, engages the adjacent side of the cap 23 forcibly closing the said cap and positioning the block in a locking position with respect to the cap, overlying the hinge portion thereof. In this manner, the fluid within'the chamber 18 may be readily sprayed forwardly of the muzzle 16 by operating the handle 22 of the squirt-gun, while the rifle 10 is held in the hands of the soldier by means of the stock 32. When the squirt-gun is not in use, the block 25 insures the closing of the nozzle 15 by means of the cap 23 and preventing any remaining fluid from escaping from the cylinder 12, the said block forming a serviceable locking means for the said cap 23 until said block is retracted.

What I claim, as new is 1. A fluid spray device comprising a cylinder, a discharge nozzle at the forward I end thereof, a reciprocating piston within said cylinder, an operating rod for the piston, a handle attached to the outer end of said rod, a hinged cap at the forward end of the cylinder adapted for closing over said nozzle when the device is not in use, and automatic closing means slidably attached to the side of the cylinder operatively connectedto the said handle for simultaneous move ment with the said piston.

2. A fluid spray device comprising a cyl inder a discharge nozzle at the forward end thereof, a reciprocating piston within said cylinder, an operatingrod for the piston, a handle attached to the outer end of said rod, a hinged ca at the forward end of the cylinder adapted for closing over said nozzle when the device is not in use, parallel guide strips upon said cylinder at opposite sides of one point of connection with said cap, a closing block for the cap slidably' mounted upon the cylinder with oppositely projecting flanges, positioned within said guide strips and having an arcuate inclined forward end adapted for engaging the cap when open during the forward movement of the block, a connector parallel with said piston rod attached between the said block and handle, the said block being adapted for positioning overlying the forward end of the cylinder and the adjacent portion of the cap in looking relations with respect to said cylinder and cap when said piston and handle are substantially at the forward end of their travel.

3. In combination with a squirt-gun hav ing a reciprocating piston rod and a discharge nozzle, a cap adapted to cover said nozzle, hinge connections between said cap and cylinder at the bottom of the cylinder, a block slidably attached to the bottom of the cylinder having a curved inclined end adapted for engaging the cap when open for closing the same and furtherhavinga bottom groove adapted for accommodating the said hinge during the forward movement of the block, a rearwardly extending rod attached to said block and an operating handle secured to the rear ends of both of said rods, the said block being adapted for overlying the, portions of the cylinder and cap adja cent the said hinge for locking the cap closed when the device is not in use.

In testimony whereof I affix my signature.
